CONFUSED about BIG baby

31 week check up 4 days ago, baby is measuring at 33 weeks 4 days! 4lbs 12 oz. Umm, am I the only one? What does this mean for when I will be giving birth? I am not diabetic or over weight. According to my LMP, I am 34 weeks as of today. But according to my baby’s measurements in the first trimester, he was measuring 2.5 weeks smaller so they gave me the due date of 1/6/2019 instead of the original al 12/20/18. OB says she will not change due date in the 3 trimester. SO (significant other) CONFUSED.

It’s just an estimate and is often a bit off. My son has been measuring at the 4 on mark since 28 weeks, and will likely be measuring 5 lbs at my next scan on Tuesday (31 weeks). I do have big babies, but I’ve never had measurements THIS big. I’m going to laugh when he comes out 6 and a half pounds full term

I measured almost 2 weeks ahead with my son, starting about the midway point. I didn’t have GD and didn’t gain an excessive amount of weight. He came 3 weeks early and was 8lbs...some babies are just bigger. He wasn’t even chunky, he was just tall and solid. He’s 2 now and has always been average weight and in the 80-90th percentile for height. At this point, baby is coming whenever baby is coming...so your doc is not likely to change your due date for that reason.

Don’t worry they can be totally off! My previous 2 were always 2+ weeks ahead and I had exact dating.. they were 9.5 & 9 lbs and delivery was really not bad. Everybody makes different sized babies and ultrasounds are not always that accurate. Trust in your body and enjoy the ride!

I’m 30 weeks tomorrow and last Friday at my scan, the ultrasound tech measured my daughter at 4 lbs 5 oz. Then when the doctor came in, his measurement was 4 lbs 1 oz, either way pretty big at 29 weeks and 99th percentile! However, I was a big baby at 9.5 lbs and my husband was around 9 as well. My first daughter was just 7 lbs 12 but I’ve been feeling like my belly is HUGE and I wasn’t wrong.

This past Tuesday my baby was measuring at five and a half pounds, two pounds more than normal for 31 weeks 4 days. Doctor told me to not buy any newborn size clothing.

While I have heard that ultrasound weights are inaccurate, my family has a history of big babies. The smallest of us was my niece and she was about 8 pounds. My brother was the biggest at more than 10 pounds. Also noted that I am overweight, but do not have GD.
